The NAND supports 32bit reads and writes so lets stop shunting 8bit
chunks across the bus.
Doing a dumb 'dd' benchmark, this increases performance roughly like so:
* read: 1.3MB/s to 3.4MB/s
* write: 614kB/s to 882kB/s

The type was IORESOURCE_IO which is not what is expected by
plat_nand_probe(). This device has not worked since 2d098a72
("mtd: plat_nand: request memory resource before doing ioremap").

Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.
The various declarations were removed using the following script:
grep -rl MACHINE_START arch/arm | xargs \
sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'
[ Initial patch was from Jeremy Kerr, example script from Russell King ]

These three platforms didn't properly fill nr_chips in gen_nand
registration and therefore depended on gen_nand bug fixed by commit

multiple chips")

Received official word finally from Technological Systems on which
FPGA ID's they have released unto the world. Also an additional of
a dummy entry matching the FPGA ID of the Verilog template on our
wiki.

Stefan Agner found his board comes with 0x00b480/0x02 but the main
board also has Rev B printed on it like my 0x00b480/0x03. Some light
enum renaming was needed but it was to be expected.

Added checks to the platform_device_(register|add) calls so that if
a device failed to load it would then not later be unloaded; also
added the hooks so that it would not try to unload when the RTC
driver support is compiled out.

the FPGA on the TS-7800 provides access to a number of devices
and so we have to be careful when reprogramming it. As we
are effectively turning a bus off/on we have to inform the
kernel that it should stop using anything provided by the
FPGA (currently only the RTC however the NAND, LCD, etc is
to come) before it's reprogrammed.
Once reprogramed, we can tell the kernel to (re)enable things
by checking the FPGA ID against a lookup table for what a
particular FPGA bitstream can provide.

The TS-7800's M25P40 is not available to the kernel, it's used
to load the initial bitstream onto the FPGA and so these hooks
point to nothing and need to be removed.

Currently, there are two different fields in the
mv643xx_eth_platform_data struct that together describe the PHY
address -- one field (phy_addr) has the address of the PHY, but if
that address is zero, a second field (force_phy_addr) needs to be
set to distinguish the actual address zero from a zero due to not
having filled in the PHY address explicitly (which should mean
'use the default PHY address').
If we are a bit smarter about the encoding of the phy_addr field,
we can avoid the need for a second field -- this patch does that.
